Accident Statistics Quantification of risk through the use of statistics.  OSHA incidence rate:  Number of injuries or work related illnesses per  200,000  hours of exposure (100 worker-years).  Only lost “work-days” are counted in the ratio.   Fatal Accident Rate (FAR):        Number of fatalities per 10 8  hours of exposure (roughly 1,000 worker  lifetimes). Fatality Rate: Number of fatalities per year divided by the  population at risk.  Example: 0.005 for smokers means a smoker has  0.5% to die  in a particular year due to smoking  related reasons.
